Foreword

GB/T 17902 "Information Technology Security Technology with Digital Signature of the Appendix" consists of the following parts. Part 1. Overview; Part 2. Identity-based mechanisms; Part 3. Certificate-based mechanisms. This part is the third part of GB/T 17902, which is equivalent to the international standard ISO /IEC 14888-3..1998 "Information Technology Safety Technology" Digital signature for appendix with appendix Part 3. Certificate-based mechanism (English version). Appendix A and Appendix B of this part are normative appendices, and Appendix C to Appendix G are informative appendices. This part is proposed by the Ministry of Information Industry of the People's Republic of China This part is under the jurisdiction of the National Information Security Standardization Technical Committee; This part was drafted by China Electronics Technology Standardization Institute and State Key Laboratory of Information Security. The main drafters of this section. Ye Maofeng, Chen Xing, Luo Fengying, Hu Lei, Ye Dingfeng, Zhang Zhenfeng, Huang Jiaying.

1 Scope

GB/T 17902 specifies a digital signature mechanism with an appendix for messages of any length and is suitable for providing raw data identification and non-repudiation. And data integrity programs. This part of GB/T 17902 specifies a certificate-based digital signature mechanism with an appendix. In particular, this section provides. 1) A general description of a certificate-based signature mechanism whose security is based on the difficulty of discrete logarithm problems on the switched groups used (see Chapter 6). 2) A general description of the certificate-based signature mechanism whose security mechanisms are based on the difficulty of factorization (see Chapter 7). 3) Various conventional digital signature mechanisms with appendices based on the certificate mechanism using arbitrary length messages (see Appendix A and Appendix B).

3 Overview

The definitions, symbols, numerical lengths and notations given in GB/T 17902.1-1999 are used in this part of GB/T 17902. The verification of the digital signature requires the verification key of the signature entity. Therefore, the authenticator must associate the correct authentication key with the signature entity. stand up. For certificate-based mechanisms, this association must be provided by some kind of certificate. For example, the verification key is taken from a certificate. The purpose of this part of GB/T 17902 is to specify the following procedures and functions of the general model described in GB/T 17902.1-1999. a) The process of generating a key 1) Generate domain parameters 2) Generate signature and verification key b) the process of forming a signature 1) (Optional) Form a pre-signature 2) Prepare a message for the signature GB/T 17902.3-2005/ISO /IEC 14888-3.1998 ......
